中文摘要：

采用真空压力浸渗技术了制备金属Ti／Mg基非晶双连续相复合材料，系统研究了其准静态和动态力学行为。并借助XRD、SEM等技术分析了该复合材料的结构和断口形貌。研究发现，该复合材料具有优异的综合力学性能，强度优于基体Mg基非晶合金和增强相Ti骨架。动态载荷下，应变速率的变化对复合材料的性能和断口形貌具有显著的影响，随应变速率的增大，复合材料的强度逐渐升高，断口上非晶相的粘滞流变现象更加明显。

英文摘要：

Ti/Mg-based metallic glass interpenetrating phase composites were prepared using a pressure infiltrating method. The quasi-static and dynamic deformation behavior was investigated, and the structures and fracture morphology were analyzed by means of XRD and SEM. Results show that the metallic glass interpenetrating phase composites have a better comprehensive performance than the porous titanium skeleton and Mg-based metallic glass under quasi-static condition. The effects of strain rate on mechanical behavior and fracture morphologies under dynamic compression are significant. The fracture strength increases as the strain rate increases, and the phenomenon of viscous flow is more obvious on the fracture.
